Laravel Bug Fixes & Enhancements

My current Laravel site is online but showing a handful of stubborn bugs and gaps in functionality. I need a seasoned full-stack developer who can dive straight into the existing PHP/Laravel codebase, trace the issues end-to-end, and push clean fixes without breaking anything else...
